Kiewit had 2012 revenues of more than $11 billion and consistently ranks among the top five contractors by Engineering News-Record. We have virtually unlimited bonding capacity and are one of the few construction firms able to compete for billion-dollar mega-projects. However, our organizational system of local operating districts enables us to also take on smaller contracts. (Source)
